How is inheritance of the MEN 2 gene diagnosed?
The most reliable way to determine if MEN 2 gene has been inherited is to do agenetic test (predictive genetic testing). Recent advances have made it possible to perform predictive genetic testing at any age. This requires only a single blood sample. The DNA in the blood sample is analyzed for the presence of an abnormal MEN 2 gene. People with an abnormal MEN 1 gene are said to have a positive result. This test can detect MEN 2 even when all other tests are normal. A negative genetic test result means that a person does not have MEN 2, nor can they pass MEN 2 to their children. Those individuals with a positive genetic test result should have regular tests for endocrine gland overactivity. Genetic testing is not usually part of routine MEN 2 blood testing. If you would like more information on the criteria for genetic testing please discuss the issue with your doctor. Genetic testing is now available for everybody in the U.S..
